Digitally Processed Videos That Make the Flight Paths of Birds Visible

Artist Dennis Hlynsky uses a digital process to make the flight paths of birds visible in his mesmerizing video project, “small brains on mass.” The process, which Hlynsky calls “extruded time,” involves stacking frames in a sequence and adding the darkest pixels together. The effect is a long trail that shows the past few moments of a bird’s flight path as it flies. Large flocks become dense clouds of paths that continually form and disappear. Hlynsky has more extruded time videos on Vimeo.
